Product Description

Product description

Applications
J641H pneumatic cut-off valve adopts double-acting air cylinder, which can control the valve remotely by air inlet in upper chamber or air inlet in lower chamber, so it is convenient and flexible to operate. Medium used in cylinder: compressed air and nitrogen. Simple structure and convenient manufacture and maintenance; Short working stroke and short opening and closing time; The sealing surfaces of the closing body (disc) and the valve seat are sealed with conical surface, which has small closing force, erosion resistance and reliable sealing. The valve seat can be a replaceable valve seat, which can be arbitrarily combined with the sealing surface material of the closing part to meet the working condition requirements and prolong the service life.

the structural characteristics
1. The material selection is exquisite, in line with relevant domestic and foreign standards, with reasonable structure and beautiful appearance.
2. The sealing surfaces of disc and valve seat are made of iron-based alloy surfacing or Stellite cobalt-based cemented carbide surfacing, which has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life.
3. The valve stem has good corrosion resistance and scratch resistance after quenching and tempering and surface nitriding treatment.
4. Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.
5. The valve body has a complete variety of materials, and the packing and gasket can be reasonably selected according to actual working conditions or user requirements, and can be applied to various working conditions of pressure, temperature and medium.
6. The reverse seal is made of threaded seal seat or body surfacing austenitic stainless steel, which is reliable in sealing, and the packing can be replaced without stopping the machine, which is convenient and quick, and does not affect the system operation.
